Basel, Switzerland, 24 April 2014 – In the first quarter of 2014, Lonza’s business performance was fully in line with our expectations. In both the Specialty Ingredients and Pharma&Biotech segments, we realized our growth targets and achieved a better performance than in the same period of the previous year. We experienced considerable translational currency impact from the strong Swiss franc, but we were able to compensate the bottom-line impact in the first quarter by productivity improvements.

Richard Ridinger, CEO of Lonza, said, “I’m pleased with the performance of our businesses in the first quarter. The good results show that we have embarked on the right path with our transformational initiatives, which make us more competitive and more market oriented. We also continue to work diligently on operational improvements and quality initiatives across the company in all regions.”

Specialty Ingredients Segment

The Specialty Ingredients segment had a good start for 2014 with positive overall market demand in most areas. In Consumer Care the Hygiene business had a particularly encouraging start. In Agro Ingredients the interest in Lonza’s development and manufacturing capabilities continued to increase and resulted in a steadily growing pipeline and strong growth in commercial sales. The Water Treatment business experienced good demand and improved profitability in Brazil, but the translational effect of the exchange rate had a strong negative impact on reported results. The overall Industrial Solutions business enjoyed good demand. The strategic review process of the Wood Protection business is proceeding according to plan with numerous interested parties.

Pharma&Biotech Segment

The Pharma&Biotech segment saw an uptake in demand across all technologies and offerings. In Custom Manufacturing several new contracts were concluded, and the start-up of second large-scale ADC facility in Visp (CH) is on schedule for Q2 2014. Microbial Development Services successfully executed the process transfer of four customer projects from Hopkinton, MA (USA) to Visp. Demand was strong throughout the first quarter for mammalian cell-line construction programs in Slough and Singapore. In our Bioscience Solutions business, we experienced a strong recovery within the European research business, whereas Lonza experienced conservative spending in the US research market. As expected, the Media business had good performance.

In summary, overall results for the first quarter, as well as our improvement projects emphasizing organic growth and quality matters, are all fully on track. Lonza’s financial situation is solid. Based on constant exchange rates, we are on track to deliver a revenue growth of ~5% and a CORE EBIT growth of ~10% in 2014.
